What is the main idea behind pyrolysis?

1 answer:

6 0

The process of thermal decomposition of organic materials (carbon based materials) at very high temperature and absence of oxygen is known as pyrolysis.

The temperature for such process is generally 430 °C or 800 °F. This causes simultaneous change in physical phase and chemical composition of the organic material. The process is irreversible in nature.

The resultant products mostly have more useful properties than the original one. Thus, to bring the greater value to the common organic material and waste, the idea of pyrolysis is important.

14.85 g of water

Explanation:

Calculate the mass of water produced when 9.56 g of butane reacts with excess oxygen.

Here we have the full oxidation of butane (C₄H₁₀) which produce carbon dioxide and water.

C₄H₁₀ + (13/2) O₂ → 4 CO₂ + 5 H₂O

number of moles = mass / molecular weight

number of moles of butane = 9.56 / 58 = 0.165 moles

Now, taking in account the chemical reaction, we devise the following reasoning:

if 1 mole of butane produces 5 moles of water

then 0.165 moles of butane produces X moles of water

X = (0.165 × 5) / 1 = 0.825 moles of water

mass = number of moles × molecular weight

mass of water = 0.825 × 18 = 14.85 g

max2010maxim [7]

Answer:

1) Anaerobic respiration

2) Lactic acid

3) Stop the work out

Explanation:

1) Anaerobic respiration

Muscular anaerobic respiration to produce energy during exercises or workout, takes place when the level of oxygen available for the amount of energy being generated is not sufficient, and the balance generated energy is produced along with lactic acid by anaerobic respiration

2) Lactic acid

The produced lactic acid from the anaerobic respiration at the muscle sites results in a burning sensation being felt during strenuous muscular activity in the presence of low oxygen supply

3) Stop the work out

In order to stop the burning, the muscular activity is to be stopped, to allow the resumption of the aerobic process of energy production, and to allow the produced lactic acid to be cleared

What type of reaction is occurring when an acid and a base are mixed together?

Law Incorporation [45]

Answer:

It is a neutralization reaction

Explanation:

When an acid and a base are mixed together the reaction occurring is called a Neutralization. It receives that name because the protons ( $H^+$ ) of the acid react with the hydroxil ( $OH^-$ ) of the base, canceling their acid and basic power, respectively.
